Topic tags/keywords: humor tip question planer milling sanding explosion

Disaster stuck my shop tonight! After five days of work on my very first cutting board it EXPLODED! Seriously! The darn thing exploded! Have you ever had a cutting board explode?

Here’s what I think happened. I was down to rough sanding it when I got in a hurry. After all, I’ve spent a lot of time watch glue dry. So I had this brilliant idea. Why do all this work with the sander when I’ve got a brand new planer sitting on the bench. I did some practice runs with it so I’m a pro. Right? I had one side fairly even but the other side had high spots, a bunch. But surely my planer would make quick work of that.

First pass I took less than 1/16” cut. It went through smooth as silk. I flipped the board over and started my second pass. BOOM! The proverbial pigeon poop hit the fan and chunks of wood EXPLODED in every direction. I had no idea woodworking could be this exciting. After I showered and changed my underwear, I went back and picked up the pieces.

Here’s what it looked like after the first glue up before the second cut to expose the end grain.

Here’s what it looks like now.

Maybe I can salvage enough to make an apple slicer board.

NCIS, I’m a Navy Veteran, completed their forensic exam and came to the following conclusions:

1. My table saw blade and fence need adjusting
2. This led to uneven and not parallel cuts.
3. The glue was sufficient, but not so much so that compression could make up for the gaps.
4. I could have gotten away with using the planer if both sides were sanded smooth and level, but then I wouldn’t have needed the planer.
5. Haste makes waist.
6
The cancer isn’t as likely to kill me as my lack of shop safety.
7. Changing my underwear was the only thing I did right.

Conclusion: NCIS recommends that I go back to Vietnam, I’ll be safer.

You need a drum sander to safely do what you attempted with an endgrain cutting board. I’d never attempt putting one in a planer for the reason you discovered. Glad you are okay.

Glad you are alright. You may want to check your planer blades. I have heard of the blades ending up damaged when someone does what you did.

I put my end grain boards through the planer all the time. In fact, I planned 10 boards last night with no issues. The trick is to take very tiny bites, have good knives and round over the back edge to prevent tear out. Patience doesn’t hurt. I’m not going to say it won’t ever happen but I have not had any issues.

Interestingly, the only blow out I have had was a piece of very plain grain maple. I got lucky and was able to get the isdue taken care of.

Long and short, planing my end grain boards saves ne a ton of time sanding.

I’m glad you were not hurt. I would cut you board down and use it as a board to cut limes for a refreshing beer.

By the way, the smallest end grain board i will put through the planer is 10” in length. Anything shorter goes through the drum sander.

Good luck.

You have to be careful when using a Planer, you should only take about a 32nd or shallower pass.

I use my planer and take very shallow passes but it really isn’t recommended.

I’m guessing you won’t be trying it again though.

glue the shit down to a substrate, be it another layer of the same pattern repeated ?

as a collective ? if we buy plywood layered in sheets of veneer ?

would we reinvent how to make plywood “

one is is inexpensive,

yours ?

not so much

it lacks common sense

Here’s what I think happened!

You have to have better glue joints.
I don’t know what happened, but your joints aren’t very tight at all. (Red Circles)

Look at how clean the breaks are (Blue Circles) Not enough glue penetration. Maybe not enough glue?

Steve,sorry about your cutting board but I’m glad you came out unscathed. BTW, I liked the look of the long grain glue-up and probably would’ve been satisfied with it at that point.

Sorry your cutting board went kaboom. You might want to check your planer so you don’t have any surprises latter. I really enjoyed reading this section “After I showered and changed my underwear, I went back and picked up the pieces.” It really scared you, eh?

Good catch Kevin,
Take a pic of the glued surface and see if it looks like there was a insufficient amount of glue.
